Re: overheating in ubuntu 12.04

Mr."pscool"my laptop's [it is new Dell Vostro 3550, with Core i5-2nd generation cpu, and with hybrid (capable of automatically switch according to needs) graphics {Intel HD3000 (inbuilt into cpu) + AMD Radeon 6600/6700 series}] overheating problem gone after installing appropriate graphics driver. Now my system (with Ubuntu 12.04) is running cooler like Windows 7. Though my system is different than your system, I think the solution method will also be applicable for your system. Because I use the same method for my different systems.
Method: It is automated driver installation procedure using "Additional Drivers".
If you unable to understand the method, then I can explain it to you.

2.
Update your system first. To do this, run following 2 commands in terminal one by one (each one will take time, so keep patience):

sudo apt-get update
sudo apt-get upgrade

3.
Restart your system.

4.
Save a backup copy of xorg.conf in case this process doesn't work (to avoid reinstallation of ubuntu).

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup

5.
Now search for "Additional Drivers" in the Ubuntu Dash Home (Unity).
Or click on wheel button located on top right hand corner of desktop "System Settings" => "Hardware" => "Additional Drivers".
The software named "Additional Drivers" will search for available drivers. A window will show you up the available drivers available for your system.
Select "your graphics driver".
Now click on "Activate".
After downloading it will install appropriate driver for your graphics system automatically.

6.
Restart your system.

7.
Now open "your installed driver software interface (after searching in unity dash home)". It may show you some error message, with valuable instructions to fix this problem. Follow the instructions using terminal.

10.
Now it will open successfully (if you followed the instructions correctly). You will be able to change the default settings of your graphics card (if you open it using sudo or in administrative mode).

11.
You will see that the excess heating problem gone, battery life increased, watch the processor fan speed.

Please post error messages (with screen-shoot), if you get in the above process. It will show exact problem which you are facing, and will help to diagnose the problem.
